If you live in an area with severe winds, then chances are you want to make sure your new roof installation can withstand the weather. Fortunately, there are several techniques that can help you create a more wind-resistant roof.
1. Sturdy Shingles
Not all asphalt shingles are created equal. Make sure that the ones you choose are rated for wind resistance. Wind-resistant shingles are rated H and feature a reinforced nailing edge to help prevent tear off in high wind events. For even more wind resistance, look into laminated asphalt shingles. These are even more durable than standard shingles.
2. Seasonal Concerns
Asphalt shingles have a special adhesive backing on them that helps seal them down to the roof decking securely. Unfortunately, this adhesive is only activated by the heat of the sun beating down on the roof. If your roof is installed during the late fall or winter, then the adhesive may not activate right away so the shingles won't be secured until the weather warms up in summer. If you must install a roof in winter, then it may be necessary to spot cement edge shingles to prevent uplift.
3. Upgraded Drip Edge
The right drip edge can reduce uplift as it creates a barrier that prevents wind from getting underneath the shingles at the eaves. A reinforced drip edge with an adhesive strip prevents shingle uplift. It's also a good idea to limit shingle overhang at the drip edge, as greater overhang increases the chance of the wind blowing up and damaging the shingles along the edge of the roof.
4. Better Nailing
Nails play a major part in the wind resistance of the roof. Your roofer will take pains to ensure nails are properly driven, as underdriven nails can easily be ripped out in high winds. Request corrosion-resistant nails, as these have a longer lifespan and are less likely to suffer wind damage.
5. Reinforced Ridges
Ridges and hips are a common area where wind uplift rips off shingles. Nails must be long enough to go through the shingles, ridge cap nailing edge, and any vent edges. It is also helpful to use an adhesive along any hips or ridges that don't have venting beneath them, as a roofing adhesive ensures there are no loose shingle edges that could be damaged by wind.
